Suspended Sediment Concentration Profile in a <i>Typha Latifolia</i> Canopy

چکیده
The transport of sediment in regions with vegetation plays an important role aquatic ecosystems and landform evolution river deltas. In this study, flow parameters suspended concentration (SSC) within emergent canopy real plant morphology (Typha latifolia) were measured a laboratory channel. T. latifolia is common marsh species multiple thin leaves emerging from tight bundle (culm) at the bed. observed equilibrium SSC profile differed significantly Rouse profile, classic model for over bare beds. vertical distribution was nearly uniform culm region canopy, decreased height upper distributed leaves. reflected vertically nonuniform turbulent diffusion, which arose morphology. A diffusivity based on cylinder arrays first validated tracer data then adapted to morphology, providing way systems. successfully used random displacement predict spatial canopy.

متن کاملEstimating Suspended Sediment Concentration in Streams by Diffuse Light Attenuation
A light attenuation sensor system (LASS) for measurements in waters is described in this paper. The LASS records irradiance at multiple levels in the water column to provide a measure of the diffuse light attenuation coefficient which is strongly affected by suspended sediment. Dimensional analysis and geometric optical theory are used to relate the irradiance attenuation to sediment properties...

The present study investigates the performances of the three-dimensional multicomponent hydro-sedimentary model ROMS (Regional Ocean Modeling System) to predict near-surface suspended sediment concentrations (SSC) in the English Channel (western Europe). Predictions are assessed against satellite-retrieved observations from raw MODIS and MERIS images for the year 2008 characterized by the highe...

To quantify the effect of wave breaking turbulence on sediment transport in the nearshore, the vertical distribution of time-averaged suspended sediment concentration (SSC) in the surf zone was parameterized in terms of the turbulent kinetic energy (TKE) at different cross-shore locations, including the bar crest, bar trough, and inner surf zone. Using data from a large-scale laboratory experim...
